Aluminum shingle accesories

Abstract

Accessories for use in installing metal shingles to a roof have convertability and simplicity features. One of the accessories can be used as a starter strip at the edge of the eaves. It can also be used as a gable strip at the end of the gables. This accessory has two flat portions formed transverse to each other with a channel located at the corner between the two sections. At the edge of the eaves, the channel is oriented on top of the decking for receving the locking flange of a conventional metal shingle. At the edge of the gable, the channel is oriented vertically, next to the fascia board, for receiving a downwardly bent edge of a conventional shingle. The valley base consists of two flat portions with an upwardly facing channel located in the center. The channel receives downwardly turned edges of the adjoining shingles.

I claim: 
     
       1. A method of installing metal shingles to roof decking at an eave and gable end, each of the shingles being of the type having a lower forwardly projecting flange for engaging an interlocking slot of another shingle, comprising: providing an accessory with first and second flat portions bent to form a corner, each flat portion having a free edge, the accessory further having a channel formed between the second flat portion and the corner;   securing one of the accessories to an eave to serve as a starter strip, with the channel and second flat portion extending forwardly above the roof decking, and with the first flat portion depending downwardly to serve as a drip edge;   securing a first row shingle to the roof decking with its flange inserted into the channel;   securing another one of the accessories to the gable end to serve as a gable strip, with its channel and second flat portion located outside the decking and extending downwardly, to serve as a drip edge, the first flat portion extending above the roof decking; and   bending the sides of the shingles next to the gable end downwardly and inserting the sides into the channel.   
     
     
       2. The method according to claim 1 further comprising: securing a spacer board on the decking at the eave, and securing the channel of the starter strip above the spacer.   
     
     
       3. The method according to claim 2 wherein the first portion of the gable strip is secured directly to the roof decking. 
     
     
       4. The method according to claim 3, further comprising: forming the accessory such that the distance from the free edge of the first portion to the corner is greater than the distance from the free edge of the second portion to the corner by an amount equal to the thickness of the spacer board.
